Referring to the" drswings, A. represents g-the body of the siug, .eommonly t-ypehigh, tidying on the tIPPQI' edge, properlyustified, {the type characters The opposite sides of the slug are formed with two, three or more eavitie's, a, for reducing the thickness of the bed o f the slug, as shownja't 03. On

The upper hedge hearing the type'characters is made of maximum width, and on both sides, overhangs the ribs a! and the cavities a These ribs "assist in supporting the upper type bearing edge, and their vertical side faces be adjusted to produce these type.'ehar-,.

asters in the required position on' the upper face.

It will frequently happen,-as illustrated in Fig. 0,, that the type characterswillv need toappenr nmch nearer one side or edge/0f the sing: than the other. In such case the sin origimlily cast of full width is reddoe from the opposite side, sis-indicated by the dotted line in said figure. When thus modilatented Nov; 26,1912.

tied it will have the proper thickness and xvii: mm the characters in proper relation to two sides. Fig. 4 il1ustrates'a slug wnu has been thus reduced from one side n;- reim-t-e the foot space, and Fig. 5 illustrai a slug reduced from the opposite side to decrease the head space without affecting the foot space.

in some special cases, Where small characters are cast on a large sing, it is advisable to reduce the slug from both sides. This is particularly advantageous, because in commercial linotype machines matrices for characters of any size may he inserted in the machine at will and reproduced on a large slug, which can then be reduced to the suitable thickness without changing the mold in the machine. It is practically impossiblefto reduce s eedily or accurately a solid or unrecessed 5 ug. The formation of cavities on hot sides has the effect not only of reducing the weight, but of reducing the area ofthe surface which must be cut away to reduce the thickness. When slugs are formed as herein shown, all with a top face of maximum width adapted to carry type characters of the largest size in common use and with recesses on both sides, it is possible to utilize the mold which may happen to he in the machine in connection with matrices which produce characters above or below the required positions, and thereafter trim the slug on one or both sides in order to reduce it to the required thickness and at the same ipesuee for special purposes matrices which could,

not otherwise he used except after changing the mold.

\Vhat I'cla-im as my invention is:' A printing slug formed with e longitudig -nal Web end recesses at both sides thereof and having a grinting edge provided with type located so stentially in the plane of the longitudinal web and also projecting portions which overhang t erecesses on both sides of the Web, so that it may be reduced or trimmed at either side.

In testimony whereof I hereunto set my hand this 22d day of October, 1908, in the presence of two attesting Witnesses.
